Unfortunatley they are not on the ITN site now.

It might have been a very temporary thing.

I used an upgrade credit for my Mrs 3 weeks ago and when I phoned the week before hand the QFF CSA said there was no U class on QF168 CNS-BNE when clearly on ITN it was show U7. I told her I was looking at an availability site and it was showing U7. She pressed a few buttons and said she found them by doing a particular class search but they were definately not on the upgrade screen when I first gave her the PRN.

So there are glitches in the system.

With all the other advice go on the waitlist and keep checking manually.

Have the number handy - it will be worth the effort if it pays off.
